M14 Route ID not working?

[Mathew Wong]

Hello,

Does anyone know how to find the correct Route ID for the M14D-SBS bus?  I think I found it in the documentation, but when I use "M14D+" as the Route ID I get a "No such route" error in the API 's response:

M14D API Response: {'Siri': {'ServiceDelivery': {'ResponseTimestamp': '2024-09-06T06:55:10.960-04:00', 'StopMonitoringDelivery': [{'ResponseTimestamp': '2024-09-06T06:55:10.960-04:00', 'ErrorCondition': {'OtherError': {'ErrorText': 'No such route: MTA NYCT_M14D . No such route: MTA_M14D . No such route: MTABC_M14D .'}, 'Description': 'No such route: MTA NYCT_M14D . No such route: MTA_M14D . No such route: MTABC_M14D .'}}]}}}

To find the Route ID I went to https://new.mta.info/developers and downloaded Manhattan's gtfs.zip file.

In route.txt, I found these Route IDs, but none of them work and all of them return the above errors.  Can someone help me figure out if I'm doing something wrong?  Thank you!

Be sure you're passing the + sign properly encoded in the URL.

This solved my problem precisely, thank you!  

For anyone else encountering a similar issue, I should have used "M14D%2B" instead of "M14D+".
